Getting the current time zone in android application [duplicate]

How can I get the current time zone in my Android application? I tried to use this

Calendar cal = Calendar.getInstance( userConfig.locale);
TimeZone tz = cal.getTimeZone();   

But I am not getting the timezone from it. How can I display the timezone?

Solution 1:

Use this

Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone();
Log.d("Time zone","="+tz.getDisplayName());

or you can also use the java.util.TimeZone class

TimeZone.getDefault().getDisplayName()

Solution 2:

String timezoneID = TimeZone.getDefault().getID();
System.out.println(timezoneID);

In my Console, it prints Asia/Calcutta

And any Date Format, I set it Like....

SimpleDateFormat sdf2 = new SimpleDateFormat("dd-MMM-yyyy");
sdf2.setTimeZone(TimeZone.getTimeZone(timezoneID));

Solution 3:

I needed the offset that not only included day light savings time but as a numerial. Here is the code that I used in case someone is looking for an example.

I get a response of "11" which is what I would expect in NSW,Australia in summer. I also needed it as a string so I could post it to a server so you may not need the last line.

TimeZone tz = TimeZone.getDefault();
Date now = new Date();
int offsetFromUtc = tz.getOffset(now.getTime()) / 3600000;
String m2tTimeZoneIs = Integer.toString(offsetFromUtc);
